The Erdos-Straus Conjecture proposes that: For n >= 1, 4/n = 1/a + 1/b + 1/c, has postive integer solutions. n = 2k (evens) n = 4k+3 (odds) n = 4k+1 (odds) For 2k I have found the pattern --> if k >= 1, 4/2k = 1/2k + 1/2k + 1/k. This is simple, I know. I am having difficulty...

What molecules or chemicals, other than water [H20] (that I know of), are less dense as they become cooler and their electrons slow? This is broad question, I know, but my question relates to the fact that much of our conditions of life rely on the density of water as it becomes a solid (see...
